Wow, what a difference 7 1/2 years makes. My 7 1/2 year old (late 2006) 17" MBP was finally biting the dust. Not bad considering the machine was turned on over 8 hours a day and many times up to 14. I only replaced the battery once after a little over 3 years. The second battery was really weak and a number of issues were cropping up like over heating, slow and a not so bright display. The new 13" rMBP is really fast and the display is awesome. The smaller display is taking a little getting used to. I've been transferring files, installing software and forwarding emails from my old MBP since 3:00pm and it's now 3:36am. The keyboard is much more responsive than the old MBP. I can't find anything to complain about, at least not yet, but I expect that I won't. It's time for bed. Night night, or should I say, good morning y'all.
